Welcome, Dear Visitor!

Don't be afraid to look around, even if a lot of the stuff on this site seems to be in german. On my blog (almost retired in 2016) I switched back and forth between english and german. And since it's all about visualisation, there is lots to explore without reading. These days you'll most likely find me on Twitter under my @wahlatlas (Election Atlas) handle.

Interested in interacting with data-visualisations on touch devices like the iPad? Here is a multi-lingual iOS adaptation of an animated population pyramid, that is not only touch enabled (changing age-groups by sliding) but the animation can also be controlled by tilting the iPad. All using touch events and the accelerometer support of mobile Safari. See a video with further explanations.
